CHP systems make sense at office buildings that are 100,000 sq. ft. and above in size, which have large enough thermal and power needs. Most CHP capacity at office buildings is natural gas-fired – 84 percent, and reciprocating engines are the primary technology being used. CHP systems are also commonly used in buildings that support business operations. For instance, a number of data centers now have CHP systems to ensure the continuity of business functions during grid outages.
